Hepatic angiography

Area of Science:

• Interventional Radiology
• Hepatology
• Vascular Imaging

Background:

• Angiographic techniques have advanced, allowing improved access to hepatic and portal venous systems with minimal complications.
• Noninvasive imaging modalities like CT, ultrasound, and radionuclide scanning have specific indications, but angiography remains crucial for certain diagnostic challenges.

Purpose of the Study:

• To highlight the diagnostic and therapeutic utility of angiography in specific hepatobiliary and vascular conditions.
• To underscore the role of angiography in evaluating portal hypertension, variceal bleeding, hepatic masses, abdominal trauma, and Budd-Chiari syndrome.

Main Methods:

• Utilizing advanced angiographic techniques for accessing the hepatic artery, portal vein, and hepatic veins.
• Employing diagnostic angiography for evaluating conditions such as portal hypertension, intrahepatic mass lesions, and suspected hepatic venous occlusion.
• Implementing interventional angiography for therapeutic procedures like embolization of bleeding varices and hepatic arterial chemoembolization.

Main Results:

• Angiography provides reliable access to the liver's vascular system with low morbidity.
• It plays a key role in diagnosing portal hypertension, variceal bleeding, hepatic masses, trauma, and Budd-Chiari syndrome.
• Angiographic interventions are effective in controlling variceal bleeding and treating hepatic malignancies.

Conclusions:

• Improved angiographic techniques offer safe and effective vascular access to the liver.
• Angiography is indispensable for diagnosing and managing specific complex hepatobiliary and vascular disorders.
• Interventional angiography provides valuable therapeutic options for bleeding varices and hepatic tumors.
